Where is Block A 180 1 of Wuhan Oriental Yijing Building? Is the number 180 1 a number 18?

I looked at the map, and it was impossible to find many buildings on the map. But I have been to many buildings in Wuchang, such as the 20th and 30th floors. I remember that the first two numbers are floors. At that time, I looked everywhere for the second floor, but there was no second floor in the elevator, and there was no floor below the fourth floor, so 180 1 was the first floor of 18. If there is a reception desk at the door, please ask, or if there is a room 180 1 on the first floor. Generally, the company of the whole building is posted on the first floor.
